CSS Mask & minify issue

I am presently using the CSS mask property and CSS minification with your plugin. What is happening is since the CSS mask utilizes the url() functionality, the minification adds in the template URL. So for example:

Unminified and working
mask: url('#mask');

Minified and not working
mask: url('path/to/theme/folder/#mask');

This is making my masks disappear completely. This is only happening in Firefox since I am able to use the -webkit prefix for Chrome and others. I was wondering if there was a hook or filter where I can exclude certain CSS properties from being minified?

Thanks in advance.
